sea level.

Ascent rate The speed at which the diver ascends toward the surface.

ASC RATE Abbreviation for ascent rate.

Ascent time The minimum amount of time needed to reach the surface on

a decompression stop dive.

ASC TIME Abbreviation for ascent time.

Ceiling On a decompression stop dive the shallowest depth to which a

diver may ascend based on computer nitrogen load.

Ceiling Zone On a decompression stop dive the zone between the ceiling and

the ceiling plus 1.8 m [6 ft]. This depth range is displayed with

the two arrows pointing toward each other (the “hour glass”

icon).

CNS Abbreviation for Central Nervous System toxicity.

Central Nervous System Toxicity

Toxicity caused by oxygen. Can cause a variety of neurological

symptoms. The most important of which is an epileptic-like

CNS% Central Nervous System toxicity limit fraction. Also note

Oxygen Limit Fraction

Compartment See “Tissue group”.

DAN Divers Alert Network.

DCI Abbreviation for decompression illness.

Decompression Time spent at a decompression stop or range before surfacing,

to allow absorbed nitrogen to escape naturally from tissues.

Decompression range On a decompression stop dive the depth range, between the ﬂ oor

and ceiling, within which a diver must stop for some time

during ascent.

Decompression illness

Any of a variety of maladies resulting either directly or indirectly

from the formation of nitrogen bubbles in tissues or body

ﬂ uids, as a result of inadequately controlled decompression.

Commonly called “bends” or “DCI”.
